Vapes and cannabis: check the law (as of 2025)

Two rules surprise visitors. บุหรี่ไฟฟ้า: as of 2025, importing, selling and possessing e-cigarettes and vape liquid are all illegal in Thailand. Police have fined and detained tourists and residents, and penalties for importing are heavy. Don't bring one in, and don't buy one from a street stall. กัญชา is more complicated. Cannabis was taken off the narcotics list in 2022 and shops opened everywhere, but the rules have been tightened since: by mid-2025, buying cannabis flower required a medical prescription, and smoking it in public could still get you fined. The law is still changing, so check current rules before you buy. All other drugs carry severe penalties, sometimes even for small amounts.
